Loose-leaf binder



April 15, 1930. c. c. ANDREWS LOOS E LEAF BINDER Filed June 14, 1928 2 VALA (1cm new S latented Apr. 15, 1930 UNITED STATES PATENT OFFICELOOSE-LEAF BINDER Application filed June 14,

This invention relates to an improved loose leaf binder or cover that isespecially suitable for the binding of catalogue pages, memorandumblanks, printed forms and the like, and

its object is to provide a loose leaf binder or cover that is attractivein appearance, is strong and durable, that is simple of construction,and is very economical of production.

More generally the object of the invention is to provide an inexpensiveloose leaf binder that possesses all of the merits of the more expensivebinders of prevailing type so that it is available at small cost for useas a binder for catalogue pages, cheap note books, etc.

The foregoing objects, with other and more specific ones hereinafterappearing, are attained in the embodiment of the invention illustratedin the accompanying drawing wherein Fig. 1 is a perspective view of myimproved loose leaf binder with a batch of leaves bound therein; Figs. 2and 3 are enlarged sectional details on the respective lines 2-2 and 33of Fig. 1; Fig. i is a fragmentary perspective view of the blank fromwhich one of the covers is made; Fig. 5 is a similar view of one of thesti'li'eners; and Figs.

6, 7 and 8 are details showing the manner of applying the stiffener tothe blank.

0 The two covers, designated 1, are identical and each is made up of asheet of suitable flexible material, such as heavy, tough paper, and astiffener that is designated 2. The stiffener may be of any appropriatematerial, such as a heavy cardboard or strawboard, wood, metal orfiberboard, though, in the interest of economy, I prefer to employ an inexpensive grade of stiff and strong cardboard.

Referring to Fig. 2, I term the portion 1 a flexible flap the portions1", 1 and 1 I term flexible layers and the portions 1", 1, 1 and 2collectively I term a binding edge portion.

In making the cover, a blank, such as that -15 designated 3 in Figs. 4,6, 7 and 8, is cut to proper size and proportions, and preparatory towrapping its edge that is to be disposed adjacent the back of the binderabout the stifiener 2, the same may be scored longitudinally along thezones indicated by the dotted lines 1928. Serial No. 285,330.

3 in Fig. 4. WVhether or not scoring is necessary or desirable dependsupon the material from which the cover is made. Before applying thestilfener 'to the blank, a suitable adhesive such as glue or mucilage,may be 5-5 applied to the area of the blank between the inner dottedline 3 and its adjacent edge, after which the stiffener is laid upon theblank contiguous to said edge, as illustrated in Fig. 6, and the edgeportion with said stiffener is then turned over to the position shown inFig. 7 and next to the position shown in Fig. 8.

Two covers are then placed together in opposed relation and punched withholes for the reception of binding posts or other suitable fasteningmeans, the binding post herein illustrated, and designated 5, being ofstandard type and consisting of a threaded stud 6 that is screwed into atubular socket member If the covers are to be applied to a batch l ofleaves at the time of manufacture, said leaves may be interposed betweenthe covers prior to the punching operation so as to insure absolutealignment of the holes in said leaves with those in the covers of thebinder.

While I prefer to glue the stiifeners to the covers as above described,this is not particu larly essential, though it is desirable principallyas a means for holding the parts to gether when the binder isdisassembled. When assembled, as illustrated in Figs. 1 to 3, the partsare secured in place by the binding posts 5.

It is evident from the foregoing that my invention provides a very cheapand simple loose leaf binder that is substantial and durable andconvenient of use, and it will be noted that whether the material of thecover is scored or not, the presence of the stiffener in the folded overback edge of the cover defines a line along which the cover will breakwhen initially opened.

Having thus described my invention, what I claim is:

1. A loose leaf binder including a cover member of thin, flexiblematerial and a narrow stiffener member, one edge portion of said coverbeing wrapped aboutand secured to said stiffener member with the edgeprojecting between the stiffener and the portion of the cover wrappedthereabout, the length of the cover in the direction of the length ofthe stiffener being substantially as great as the length of saidstiffener.

2. A loose leaf binder including a cover member of thin, flexiblematerial and a narrow stiffener member, one edge portion of said coverbeing Wrapped about and secured to said stiffener member with the edgeprojecting between the stiffener and the portion of the cover wrappedthereabout, the length of the cover in the direction of the length ofthe stiffener being substantially as great as the length of saidstiffener, said edge being cemented to the portion of the cover memberadjacent thereto.

3. A loose leaf binder including a cover member of thin, flexiblematerial and a narrow stiffener member, one edge portion of said coverbeing wrapped about and secured to said stiffener member with the edgeprojecting between the stiffener and the portion of the cover wrappedthereabout, the length of the cover in the direction of the length ofthe stiffener being substantially as great as the length of saidstiffener, said stiffener and portions of the cover member wrappedthereabout being provided with holes for reception of binding posts.

In testimony whereof, I hereunto affix my signature.
